Myths are not really involved here. The IBM PC hardware specifications are fairly well defined and the various bits of "we glued a 2Mhz part onto the bus" stuff is all well documented. Nowdays its more complex because most kbc's aren't standalone low end microcontrollers but are chipset integrated cells or even software SMM emulations.
The real test is to fish out something like an old Digital Hi-note laptop or an early 486 board with seperate kbc and try it.
